In this question we are asked to find the ratio of the number of chocolates which Lauren liked and the total of chocolates.
We know she doesn't like coconut and toffee, so she likes caramel, mint and cherry. When we count the ones she liked, we got

.
When we add to find how many chocolates are there, we got

.
To find the ratio we need to divide the first one and the second one:

is our probability.
Rounded to the nearest tenth would be one since the four isn't higher. So the answer would be 10,386.1. You did mean the tenths place right?? because could have also meant tenth(8)
The logarithmic expression of 4^(1/2) = 2 is 
<h3>How to rewrite the expression?</h3>
The expression is given as:
4^(1/2) = 2
Take the logarithm of both sides
log(4^(1/2)) = log(2)
Apply the change of base rule
1/2log(4) = log(2)
Divide both sides by log(4)
1/2 = log(2)/log(4)
Change the base

Rewrite as:

Hence, the logarithmic expression of 4^(1/2) = 2 is

Monday's gas, $3.80 rounded to the nearest tenth of a dollar would be $3.80 (its already there)
Tuesday' gas, $3.85 rounded to the nearest tenth of a dollar would be $3.90
Hope this helps!! and if you ever need anything else just ask! :)
The equation of function g(x) in terms of f(x) is g(x) = -3[f(x)].
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given:
genera form of an exponential function is y=aeᵇˣ
Now, equation for f(x) is
f(x) = 
Similarly, graph for g(x) is
g(x) = 
Comparing the two function a relation can be establish
g(x) = -3[f(x)]
